The Middle Market Power Index series analyze the characteristics and economic impact of middle market enterprises—defined as businesses generating between $10 million and $1 billion in revenues. Data for these reports are drawn from Dun & Bradstreet’s database of commercially-active businesses, which is updated on a monthly basis.

While small in number — accounting for only about 1% of all commercially-active companies — middle market firms make an immense impact on the economy. These firms employ more than one-in-four U.S. workers and generate more than one quarter of all U.S. market revenue. Yet despite their importance to the health of the U.S. economy, middle market firms are often overshadowed by their smaller and bigger siblings. Underappreciated no more, The Middle Market Power Index series of reports highlight their contributions.
